The Cross-Starter allows you to aim in-game even more precisely than the Mag-Starter.

We invite you to join our [**Discord**](https://discord.com/invite/kAsGHs2) community for any question or directly contact us through our [**support service**](https://protubevr.com/en/content/6-customer-support-hub) on [**our website**](https://www.protubevr.com/).

Upgrading to the Cross-Starter

should take you 5 minutes.

For video setup,

[you can check our YouTube Playlists](https://www.youtube.com/channel/UCnrBJ8KQE3-JQrwVBib7J-w).

First, make sure you work in a clear area and be very careful. Some parts can get lost easily.

</td><td>Bonjour, camarade joueur !

Si tu lis ceci, c’est que tu es prêt à améliorer ton Pro/Mag-Starter et à augmenter ton confort de jeu. Et nous t’aiderons à le faire !

devrait te prendre 5 minutes.

Pour la mise en place en vidéo,

[tu peux consulter nos Playlists sur YouTube](https://www.youtube.com/channel/UCnrBJ8KQE3-JQrwVBib7J-w).

Tout d'abord, assure toi de travailler sur une zone dégagée et sois très prudent. Certaines pièces peuvent se perdre facilement.
